Superbad/Adventureland director Greg Mottola‘s next film is shaping up to be the funniest geek comedy ever filmed. But before I get into the new casting, let me tell you a little about the movie.

Scripted by and starring Simon Pegg and Nick Frost (the duo from Shaun of the Dead and Hot Fuzz) as two British nerds, fresh off a trip to Comic Con, who decide to go on a road trip to Area 51. They meet an alien named Paul who asks them to help him escape from the U.S. Government. I’ve heard the script is laugh out loud funny, with tons of references to Aliens, Star Wars, and Back To The Future. So how can it get any better than that?

Seth Rogen, Jason Bateman, Kristen Wiig, Bill Hader and Jane Lynch have been cast in the movie. Rogen will be providing the voice for the alien creature, and we can only assume that Bateman, Wiig, Hader and Lynch will either play government officials or characters they meet along the way on their road trip adventure.
